Raspberry production has a long tradition in the Republic of Serbia, and the raspberry is the most economically important berry crop. According to data for the period from 2006 to 2016, the Republic of Serbia was ranked fourth in the world in the production of this fruit crop. The paper presents an analysis of raspberry production in the Republic of Serbia using statistical data from the previous years, which were compared with 2016 data. For comparison and analysis, we used the data presented on the FAOSTAT statistical database website and the Statistical Office of the Republic of Serbia (RZS) website. The analysis of the available data for the period 2006-2016 shows that the total yield of raspberries in this period varied, as did yield in tonnes per hectare, which ranged from 5.3 to 6 tonnes, depending on year. A sudden decrease in total yield in 2012 and in all subsequent years until 2016 was also observed. This was caused by a sudden reduction in the area under raspberries. [ABSTRACT FROM AUTHOR]

The subject of this study are two-year results of the oil yield of six NS soybean genotypes, 0 and I maturity group (MG) at two growing localities (Rimski Sancevi and Sombor in Serbia). Sombor had higher oil yield than Rimski Sancevi (by 119 kg ha-1, i.e. 15.97%). In the locality of Sombor, in 2010, of the oil yields were statistically significantly higher (1.088 kg ha-1) compared to 2009 (640 kg ha-1), which is higher by 448 kg ha-1 or 70% of the average oil yield in 2009. The average oil yield, for all tested genotypes at both locations was 805 kg ha-1, and ranged from 745 kg ha-1 (Rimski Sancevi) to 864 kg ha-1 (Sombor). At both sites significantly higher oil yield was recorded in 2010 compared to 2009. The highest average oil yield at both sites was achieved growing genotype Sava (840 kg ha-1). Sava had highest oil yield (887 kg ha-1) and Balkan (902 kg ha-1) in locality of Sombor. On average for both genotypes and growing localities I MG had higher average oil yield of 29 kg ha-1 (3.67%) than 0 MG genotypes. Realizing the potential for soybean productivity depends on genetic factors, the cultural practice implemented, meteorological conditions and the growing localities. [ABSTRACT FROM AUTHOR]

This study shows analysis of winter hexaploid triticale varieties (Kg 20, Favorit and Trijumf) from Kragujevac, Serbia. Varieties were grown in the trial field of Small Grains Research Centre, Kragujevac during the season 2007-2008. The best parametar of productivity for spike width, grain number in spike, and grain weight per spike was achieved by the analyzed variety Favorit, while variety Trijumf had the best parametar for spike length. Check variety (Kg 20) had the greatest spikellets number in spike. Highly significant differences were found between the varieties for width of spike and number of grains per spike and significant differences for length of spike. Triticale varieties showed no significant differences in spikellets number in spike. [ABSTRACT FROM AUTHOR]

Th is paper presents the results of soil fertility analysis on the production plots of the city of Kragujevac, Serbia. Th e analysis was conducted on a total of 467 plowland samples. Th e acid soil reaction, which belongs to the fi rst three classes in the applied classification, was found in 86.56% of samples. On average, neutral soil reaction, which is the most favourable type of reaction for crop production, was found in 15.63% of all samples in this study. Regarding soil humus content, the results show that 59.54% samples are well supplied with humus, while 35.77% of the samples belong in the class of mostly slightly humic. Considering the readily available phosphorus content, the analysis showed that only 6.34% of the soils in the province have an optimum supply of this element. What is of concern is that a considerable proportion of our samples were determined to be either very poor (57.12%) or poor (19.28%) in phosphorus, while about 10% had harmful or toxic levels of this macronutrient. In the case of the levels of readily available potassium, the largest number of the samples had either an optimum or high supply of the element. Th e sum of such samples ranged from 54.54% to 97.73% depending on the area. [ABSTRACT FROM AUTHOR]
